Abstract: A negative-working, radiation-sensitive mixture is provided which contains an organic polymeric binder and a substance which converts radiant energy into heat, wherein the polymeric binder essentially comprises units of the formula (I): in which R1 is a hydrogen atom or a (C1-C4) alkyl radical, X is a single bond or a (q+1)-valent radical of a (C4-C10) alkane, in which individual methylene groups may be replaced by hetero atoms, of a (C2-C8) alkene or of an isocyclic or heterocyclic, saturated or unsaturated, mono- or polycyclic (C6-C10) ring or ring system, n is from 40 to 80 mol %, m is from 15 to 30 mol %, p is from 1 to 10 mol % and q is an integer from 1 to 3, where q is equal to 1 when X is a single bond, and the polymeric binder has an acid number of from 5 to 150. A recording material comprising a substrate and a layer of this mixture, and a process for the production of a color proof are also provided.

Abstract: The present invention relates to a development material by means of a latent, colored image, obtained by laminating another, photopolymerizable material colored in a primary color onto an image-receiving material, peeling-off the film support and exposing the material under the associated negative color separation film, can be developed by laminating the development material onto the latent image and then peeling-off the development material together with the non-image areas. The invention also relates to a process for the production of a color proof using this development material in combination with photopolymerizable materials in the various primary colors.

Abstract: A method for producing a positive as well as a negative multicolor color-proof image.The invention relates to a color proofing process in which a multicolor image is produced from a plurality of single-color images in register with the aid of a colored, photosensitive, photopolymerizable material on an image-receiving material. Depending on the processing variant, both positive and negative film masters can be processed, even simultaneously on a single receiving material, and it is not necessary for the emission spectrum of the light source to be variable.
